Latest Patents
Philip J Questad holds a patent for a signal coupler. This invention is designed for coupling tone, voice, and other signals to a pair of communication wires, such as the tip and ring leads of a telephone line. The signal coupler comprises a gyrator, a capacitor, and a controllable voltage source. The capacitor and controllable voltage source are series connected to the input of the gyrator. The controllable voltage source is modulated by the signal to be coupled, which in turn modulates the input of the gyrator. The output of the gyrator is connected across the pair of communication wires, allowing the gyrator to modulate the loop holding current in accordance with the nature of the signal to be coupled. As a result, the signal is effectively coupled to the communication wires. Philip J Questad has 1 patent to his name.
